studio460, thanks for the advice. From their mail they already seem ready to service the camera. It's basically useless for long exposures unless I want to put up with the NR feature every time, but that doesn't even help until >10s. I will ask that the sensor (or entire body) is definitely replaced, not just "calibrated" somehow.

As a semiconductor test engineer I know exactly the reasons for this kind of thing. And the tests that would find it (on a probably-very-expensive-tester, or done manually by a person) take the longest time = therefore the most likely to be removed too early, in order to ramp volume production. :-)

I have had the same problem, noticed in the first days of shooting, other than that I've also had few hot pixels (real ones) one hot pixel in darker (not black or extra dark) videos and strange "drops" (like the ones seen on few Pentax K5) using medium/long exposures and small apertures.

I've serviced the d7000 and it should be coming back to me in the next days.. all they did (standing to what they told me) is calibrating the sensor.. :S
I'm quite sure I will still have this 'snow pixels' and the drops.

Any update to this?
I just received my new D7000 and it does have the hot pixel during long exposure. I took a few photo from 6s to 20s iso100, I notice those hot pixel is actually at the same spot. Wonder if there is no fix to it? or its just problem with some of the D7000?

Just managed the get myself registered so that I can share my experience with my D7000. Yes, my D7000 did suffered the hotpixel issue. Not really on the video part but in the still image, which was very dissapointed to know that. I realised the problem after I had purchased my tripod and doing some long exposures to capture some stars. At first I was quite excited on the result as in first time doing star shooting. Then I realised something wasn't right. There were actually more than 30 green or red dots captured even in the speed as fast as 4s, don't even mentioned abuot 30s. So I sent my D7000 back to the service centre and the technician updated camera software version, then confirmed that my D7000 CMOS needed to be replaced. Now I had collected back my D7000 after a week. I wouldn't say it is now perfect, but now only have about 4-5 dots slightly visible after 15s. Knowing that hotpixel is quite common in long exposure, but with a new and relatively-not-cheap D7000 that has so many hotpixels even in 4s exposure, to me it is a dissapointment.

#1 whenever the f-stop preview button is accidentally hit my sb900 (when mounted) will have a lengthy dump of the capacitor in where the strobe will be "on" for a few seconds. It was a huge annoyance at the black tie event I shot Friday...

My D90 and D200 don't do this...

Second qualm is that when I turn it off the camera will often keep the top LCD info on for a minute after it is turned off. It seems to do this in warmer weather. My D90, D200, and D80 (as well as the D700, D70ses, D40x, and D3100 I've used extensively don't do this...

#1 sounds like you have modeling light turned on for the preview button. You can disable this in the menu.

#2 If the camera is still writting to the SD card from the buffer when you turn off the camera, the camera will stay on until the buffer is done writing to the SD card.

As to #2 It is definately not that as I know when it is writing to the buffer. It will do it even if I havent shot anything for a while. Believe me I know when it is writing to the buffer as the green light stays on and the whole camera doesn't fully shut down(all of my cameras do this from time to time).

On this body it shuts everything but the top lcd as if it is writing to the buffer but there is nothing to write. It even does this when there are no cards in the camera and the shutter is locked...

That is a glitch.

Weird. Does the top LCD show all the info or just the remaining shots left on the card? It's normal to have the LCD show remaining shots on card all the time. I'm sure you're aware of this as this is probably not what you're reffering to. We have 2 D7000's and have never had a problem with them.
